Ground Deformation Control Technology for EPB Shield Tunneling in Complex Strata of Clay and Sandy Soil

Ground deformation rules of complex strata consisting of clay and sandy soil induced by EPB shield tunneling were studied in detail, with the second-phase project of Beijing metro Line 10 taken as background. Key parameters of shield machine were analyzed, such as earth pressure, quantity and pressure of synchronous grouting. These results are of theoretical and constructional importance for tunnel projects and can be referred to by similar studies.
